    Description / Table of Contents: Résumé Certains types sélectionnés deMetarhizium anisopliae ont été cultivés sur des grains d'avoine et examinés en tant qu'insecticides biologiques au cours d'expériences pratiques contre lesOryctes rhinoceros. Les résultats ont montré queM. anisopliae peut survivre sur les matériaux du lieu de culture pendant au moins vingt-quatre mois, leur survie n'étant pas particulièrement affectée par le type de matériel ou par les facteurs saisonniers. Les lieux de culture naturels ont été examinés trois mois après qu'ils aient été traités superficiellement par l'inoculum de grain d'avoine deM. anisopliae. La plupart des lieux de culture contenaient seulement des cadavres de larves d'O. rhinoceros tués par le champignon tandis que certains autres contenaient à la fois des larves malades et des larves en apparence saines. L'utilisation deM. anisopliae est recommandée dans le cadre du programme général de lutte contre cet insecte nuisible qui s'attaque à la noix de coco.
    Notes: Abstract Selected strains ofMetarhizium anisopliae (Metsch.) Sor. were grown on oat grain and tested in field experiments againstOryctes rhinoceros L. It was found thatM. anisopliae survived in breeding site materials for at least 24 months, with survival not greatly affected by the type of material or by seasonal factors. Naturally occurring breeding sites were examined 3 months after they had been surface treated with oat grain inoculum ofM. anisopliae. In most sites all the larvae had been killed by the fungus while some contained both diseased and apparently healthy larvae. Recommendations are made for the use ofM. anisopliae as part of a general control programme for this coconut pest.

    Studies on the susceptibility ofOryctes rhinoceros to some entomogenous fungi (1976)

    Description / Table of Contents: Résumé Des cultures deMetarhizium anisopliae, deBeauveria bassiana, deB. tenella, d'Aspergillus fumigatus et dePaecilomyces farinosus ont été examinées en fonction de leurs effets pathogènes surOryctes rhinoceros. Toutes les cultures à spores longues deM. anisopliae isolées desOryctes spp. ont été également pathogènes pourO. rhinoceros. La plupart des 23 cultures à spores courtes obtenues à partir d'autres insectes ont causé des lésions sur les larves d'Oryctes mais cinq seulement ont été mortelles. Certaines souches deBeauveria ont causé des lésions brunes sur les larves mais, en général, ces larves ont donné des adultes normaux. Une culture deB. bassiana isolée deCarpocapsa pomonella a tué les larves au moment de leur métamorphose en chrysalides. Les cultures d'A. fumigatus et deP. farinosus n'ont pas eu d'effet pathogène. Une méthode de culture deM. anisopliae sur avoine pour l'utiliser sur de grandes surfaces est décrite.
    Notes: Abstract Cultures ofMetarhizium anisopliae (Metsch.) Sor.,Beauveria bassiana (Bals.) Vuill.,B. tenella (Delac.) Siem.,Aspergillus fumigatus Fres. andPaecilomyces farinosus (Dicks, exFr.) Brown & Smith were tested for pathogenicity toOryctes rhinoceros L. All the long spored cultures ofM. anisopliae isolated fromOryctes spp. were equally pathogenic toO. rhinoceros. Most of the 23 short spored cultures from other insects caused lesions onOryctes larvae but only 5 isolates were lethal. SomeBeauveria isolates caused brown lesions on larvae but generally these larvae developed into normal adults. One isolate ofB. bassiana fromCarpocapsa pomonella L. killed larvae at the time of pupation. Cultures ofA. fumigatus andP. farinosus were not pathogenic. A method for growingM. anisopliae on oats for large scale field use is described.

    Fungal endophyte-infected grasses: Alkaloid accumulation and aphid response (1990)

    Notes: Abstract The occurrence of the alkaloidsN-formyl andN-acetyl loline, peramine, lolitrem B, and ergovaline and the response of aphids to plants containing these compounds were determined in species and cultivars ofFestuca,Lolium, and other grass genera infected with fungal endophytes (Acremonium spp., andEpichloe typhina). Twenty-nine of 34 host-fungus associations produced one or more of the alkaloids, most frequently peramine or ergovaline. Three alkaloids (lolines, peramine, and ergovaline) were found in tall fescue and in perennial ryegrass infected withA. coenophialum, while peramine, lolitrem B, and ergovaline were present in perennial ryegrass and in tall fescue infected withA. lolii and inF. longifolia infected withE. typhina. WhileA. coenophialum andA. lolii produced similar patterns of alkaloids regardless of the species or cultivar of grass they infected, isolates ofE. typhina produced either no alkaloids or only one or two different alkaloids in the grasses tested. Aphid bioassays indicated thatRhopalosiphum padi andSchizaphis graminum did not survive on grasses containing loline alkaloids and thatS. graminum did not survive on peramine-containing grasses. Ergovaline-containing grasses did not affect either aphid.
